With less than 100 years to live, I realized my writing needed to become more concise.

I also have the attention span (but not the legs) of a centipede, as do many blog readers. My "centesimals" will be opinions, rants, stories, questions, or confessions (as penance for the rants), in exactly 100 words.
Because I've also realized (through trial and error - mostly error) that I'm not the center of the universe, in an uncharacteristic attempt to achieve balance sans vanity, I won't be the central character, and there won't be a central theme.
Goal - 100 blogs in 100 days.
